Oregano Oil potent to get rid of skin infections?

half the time i am found scratching my arms legs and the sides of my face,and now you can see spots all over my body . I keep on itching till it produces a burning sensation which then leads to skin infection . since my skin is so sensitive to any kind of cream  ,i have found a way,that why dont i use oil on my body for it. then my  gym friend told me to search for oregano oil. what are the benefits that oregano oil gives? in what manner can it remove these chicken pox look alikes from my skin? how can oregano oil  be compared to oils like cocunut oil and olive oil for skin nourishment?
